1 claim.

This invention relates to improvements in soldering lugs o f thetype/used in connectionwith4 certain units of electrical apparatus.

The chief oblect of .my invention relates improved solderinglugrofsimple construction having novel features facilitating solderingof a lead wire or wires thereto.

Other objects and features of my invention will be apparent frominspection of the drawing and specification hereinbelow set forth.

Referring to the drawing, in which I have illustrated a preferredembodimentA of my invention:

Fig. 1 is a front plan view partly in section of an electricalinstallation embodying my inven-` v Fig. 2 isa bottom plan view of theinstallation shown in Fig. l;

Fig. 3 is a side televation of my improvedrsoldering lug per se showinga preferred method of assembling lead wires with the lug prior tosoldering the wires permanently thereto;

Fig. 5 is a bottom plan view of the installation shown in Figs. 3 and 4;

Fig. 6 is a bottom plan view of my improved soldering lug with the leadwires omitted;

Fig. 7 is a sectional view taken along the line 'I-l of Fig. 6; and

Fig. 8 is a perspective view of a portion of my improvedlug. d

Referring to my preferred installation illustrated in Figs.l 1-3, I haveshown an electrical unit such vas a condenser can I secured in spacedrelation to a support such as a mounting plate 2 man* h ythe.support 8.The condenser can I has a pe- Y, 'ripheral fiiange I2 adjacent its lowerend within whichare maintained a pair of insulating plates I3 and Il(Figi).

The lmounting means for attaching member 3 forse'curing the condensercan I to a support yforms no part of my present invention as it belongsto another inventor who has filed an application on the same. Theattachinggmernber 3 has been illustrated and described herein merelyincidentally to the detailed description of the type rof electrical unitwith which my soldering lugs are preferably used.

Referring in detail to my preferred construction of the solderingterminals Il, I have shown one which is made from one piece of sheetmetal Aand comprises a .relatively flat body portion I5.

An attaching means -in the form of a ange or foot portion I6 integrallyjoined to one end of the body portion extends in right-angular relationto the -normalplane thereof, as most clearly shown in Figs.'3 and 7. Thefoot portion I6 is ladapted to be held between the insulating plates bymeans of an attaching member 3 assembled I with the condenser 'canadjacent its lower en d and providing a plurality of projecting portionsI projecting beyond the lower end of thecan and through 'the plate 2 andproviding means engaging the vrear face 5 thereof. The mounting plate 2,which may be of 'metal or plastic material, hasa central opening 6 and aplurality of nai-row openings I disposed around thev opening i forreceiving'the projecting portions I. The mounting plate 2 is in turnsecured to a. panel 8,which may be a part of a radio set, by anysuitable means such as the rivets 9. 'I'he panel I has an opening III inAalignment with the opening 6.- My improved soldering terminalspermanently to the body o'f the terminal.

I3 and I4, as shownv in Figs. 1 and 3, so as to maintain the terminal inassembly with the condenser can and in upright position. A pair ofspaced wing. portions I'I integrally joined to opposed side edges of thebody portion I5 extend out of the normal plane of the body portion onone side thereof. The wing portions Il are adapted to be bent to embracea connecting lead (not shown) between the foil of the condenser and thesoldering terminal after which, if it is desired, the connecting leadmay be soldered The connecting leads are adapted to extend from the foilof the condenser through openings (not Shown) in the insulating platesI3 and I4 so as to lbe disposed intermediate the respective pairs ofwings I 1, after which the wings are bent to embrace the same. Integralwith the opposite end of the body portion I5 from the foot portion I6 Ihave provided an outwardly-extending wire-supporting means or lipportion I8. The

" lip portion extends beyond one side of the body portion and has alower open face I9 adapted to support the bare wires 20 on the leads 2|so that the bare wires may be soldered thereto. 'I'he lower face I9 ispreferably of concave shape in longitudinal cross-section providing apocket for receiving the wires 2|! so that they will naturally bunchclosev together prior to application of solder thereto, as most clearlyshown in Figs. 4 and 5.

A preferred method of applying the wires 20 to the soldering terminalsis carried out either by extending them through an opening 22 oi thebody portion l5, as shown in Fig. 4, and then bending them to disposeportions of the same near their free ends within the concave surface I9or by wrapping them around notches 23 prior to disposing them within theconcavity. The wires 20 are permanently secured to the terminals byapplying solder to the terminals at the lip I8, As a result of theparticular, construction o! my improved terminal wherein I have providedthe concave lip portion '|I, a desirable terminal is effected throughreason of the fact that the bare wires of the leads may be held in closeproper relationship until ready to be soldered thus avoiding becomingunduly separated or even slipping from place. Also, the open face I9oiers a substantial amount of surface to which the wires may be easilysoldered. Finally, the lip portion permits a visible inspection of thesoldered connection from a point immediately beneath the lip. This lastfeature greatly facilitates inspection of wire connections in radio setsduring final checking prior to saleor upon repair.

Although I have set out the preferred use of my improved solderingterminals in connection with an electrolytic condenser, it is understoodthat the lugs may be used in combination with other forms of electricalunits of manufacture.

Although I have illustrated and described a preferred embodiment of myinvention, I do n wish to be limited thereby because the scope o myinvention is best dened by the following claim.

I claim: 4

A soldering terminal having an elongated body portion, attaching meansadjacent the upper end of said body portion for attaching said terminalto a supporting means, said body portion having means adjacent the lowerend receiving lead wires prior to soldering said wires to said terminal,and a lip portion integral with the lower end of said body portion forreceiving and supporting said wires and extending transverse to thelength oi' said body portion, said lip portion having a lower opensurface extending in angular relation to said body portion to whichsolder may be applied to secure said wires to said terminal, and saidlower surface of said lip portion being concave in shape thereby to holdsaid wires closely together prior to application of said solder thereto.
